KO4700
Series
The housing shell has molded printed circuit
board guides to save time when inserting
printed circuit boards, prevent misconnections
and to keep the boards from moving. Integral
tabs on the bottom of the shell further help to
hold boards in place, eliminating lateral
movement. KO4700 housing shells can be
potted.
Printed circuit boards can be mounted in three ways:
• Behind the Front Cover
• Horizontally
• Vertically
Depending on the enclosure type, one board can be mounted
directly behind the front cover (parallel to the DIN rail).Boards can
also be mounted horizontally (parallel to the DIN rail) or vertically
(perpendicular to the DIN rail). (Refer to the Ordering Pages for
board patterns and location of board guides.)
The housing cover
snaps onto the housing
shell. Two keyed tabs
lock the cover firmly in
place. Removal of the
cover is possible for
service and repair.
Ideal for industrial applications. Small to large in size, KO4700
enclosures can accommodate 8 to132 terminals for field wire
connections. Series KO4700 enclosures can be customized to the
exact number of terminals required. Standard enclosures are
equipped with the maximum number of terminal strips and
terminals.The KO4700 series are available with two types of
terminations for connecting external wires. The Pressure Plate
type terminals,with a center line spacing of 9mm (.35 in.) and the
Box Clamp design, which has a 5mm (.19 in.) center line spacing
for much higher density.

COVER DESIGNS
Single piece, tan color covers are typically used with the smaller
enclosures. They incorporate terminals and connections to the
inside of the enclosure. In some of the smaller enclosures, the
cover doubles as a plug. A printed circuit board can be mounted
directly behind the front cover. This board is ideal for mounting
components used for
setting, adjusting and
monitoring
such
as
switches, potentiometer,
LEDs and LCDs. There is
no interferance with any

Connectors
Modular covers consist
of a one-piece tan frame with matching flat front panel. Some
versions have a front cover panel that is removable and offered in
matching tan or clear. The front covers can be custom imprinted
or marking plates can be produced and installed behind the
transparent front cover panel.
Card Edge
TERMINAL DESIGNS
Select from Pressure Plate or Box Clamp terminals with wire
protectors, and fixed or pluggable terminal-to-board connections.
(Please refer to the Ordering Pages). Removable fixed or
pluggable terminal strips can be replaced by terminal plugs if not
all of the external connections of the standard enclosure are
needed. The terminal screws used with both the pressure plate
and box clamp designs can be operated with a flat tip or a #1 or
#2 Philips type screwdriver.

KO4700 Series
Pressure Plate Termination
Terminal Screw
This type of terminal consists of a
pressure plate (captive to the terminal
screw) and the terminal bottom. The
Wire Entry
pressure plate rises automatically when
the screw is loosened. One or two
Solder Pin
wires, of equal or different sizes up to
PC Board
2.5mm
2
(14 AWG) can be terminated.
The grooved corners of the pressure plate ensure positive
retention of wire(s). The flat bottom of the terminal extends to the
inside of the enclosure and connects the terminal to the board(s)
inside.
Box Clamp Termination
The box clamp terminal accepts wires up to 4mm
2
(12 AWG).
When the terminal screw is tightened, the serrated bottom of the
wire protector pushes the wire to be terminated against the
serrated busbar. The busbar extends to the inside of the enclosure
to provide the terminal-to-board connection.
TERMINAL-TO-BOARD CONNECTIONS
The KO4700 Series offers fixed and pluggable terminal-to-board
connection possibilities. (Please refer to the Ordering Pages on the
following pages for your selection.)
Fixed Connections
Fixed terminal-to-board connections can be made by Wire
Jumper, Fast On tabs, Solder tabs, or Machine Solderable Pins.
Fast On
tabs, 2.8mm (.11in.) accept industry standard Fast On
connectors.
Use

can

the danger of misconnected wires and downtime.
MOUNTING
The KO4700 Series enclosures are designed to be mounted on
standard 35 x 7.5mm DIN rail but will also fit on the 35 x15mm DIN
rail. The extra high enclosures should be mounted on the deeper,
35 x 15mm DIN rail. (Refer to the Ordering Pages on the following
pages to determine the correct size rail for the enclosure you
select.)
KO4700 series enclosures can also be panel mounted using pull-
out tabs on the base of the
enclosure. One tab is factory
installed on each enclosure.
Up to a total of 6 pull-out
TS35 x 7.5
TS35 x 15
mounting tabs can be
installed (See Accessories)
(Refer to page 49 for mounting instructions.)
7.5mm
(.29 in.)
MARKING
KO4700 enclosures have a flat center area on the cover for
marking and mounting of components. Several types have
removable front cover panels, which can be marked at a separate
location. Imprinted marking plates can be used in conjunction with
the transparent, removable cover panel.
ACCESSORIES
• Terminal Cover Strips
• Pull-Out Panel Mounting Tabs
• Screws for Mounting Printed Circuit Board
• 35 x 7.5mm DIN Rail
• 35 x 15mm DIN Rail
CUSTOMIZATION
Enclosures can be customized to the exact number of terminals
needed. We can punch, drill or cut custom cutouts and holes for
potentiometers, switches, LEDs or LDCs. Custom colors and
special markings are also available. Please call us for further
information.
Machine Solderable Pins
can be machine soldered to the board
in the same step as the other components, saving assembly time.
The metal parts of the terminals are supplied as separate strips
which snap into the terminal housing after soldering.
Pluggable Connections
The pluggable terminal strips of the KO4700 series fit across the
width of the enclosure and plug directly into the board(s) by using
a Card Edge connector. Enclosures equipped with pressure plate
terminals also provide Solder Tabs for terminal-to-board
connections when mounting an additional board directly behind
the front cover. A Wire Jumper can be soldered to these tabs as
well.
For better retention, the strips have captive screws at each end

MODULAR ENCLOSURES
(pages 32-39)
A group of modular enclosures is available in the KO4700 series. These enclosures can be ordered in a variety of terminal arrangements
allowing for many different customized configurations. Terminal sets are available in 3, 4 and 7 pole blocks as well as blank blocks without
terminals. High Current terminals are also available on some models. This modular terminal design allows anywhere from 0 to 56 terminals
for field wire connections.
The KO4700 modular enclosures have the same design features of the standard series as well as the same materials. The terminals are
of the box clamp style. The standard terminals feature pluggable connections while solder connections are used on the high current
terminals. Printed circuit board placement is horizontal (parallel to the DIN rail) or vertical (perpendicular to the DIN rail).

Ordering Information
The modular enclosures are ordered in separate pieces. A complete enclosure consists of a base, cover frame*, cover panel* and the
appropriate number of terminal blocks. Standard terminal blocks can be ordered as blank blocks with no termination points or with 3, 4,
or 7 terminations. High current terminal blocks are available on some models. Theses blocks can also be ordered as blank blocks with
no terminations or with 3 terminations. (Please refer to the Ordering Pages on the following pages for a list of how many blocks should
be ordered per enclosure).
* High current versions have one piece center cover section instead of this two piece design.
